Abstract

A high performance induction plasma torch comprises a cylindrical torch body made of cast ceramic or composite polymer, a coaxial cylindrical plasma confinement tube located inside the torch body, a gas distributor head secured to one end of the torch body to supply the confinement tube with gaseous substances, a cylindrical and coaxial induction coil completely embedded in the ceramic or polymer material of the torch body, and a thin annular chamber separating the coaxial torch body and confinement tube. This confinement tube can be made of pure or composite ceramic materials based on sintered or reaction bonded silicon nitride, boron nitride, aluminum nitride or alumina, or any combinations of them with varying additives and fillers. The annular chamber is about 1 mm thick and high velocity cooling water flows therein to efficiently cool the plasma confinement tube.
